Q:How do you see the size of electric motors?

First of all, make sure that your electric vehicle controller is matched, with unlimited speed and current limiting device. If the controller can not meet the power of 800W, then it is useless to change the motor only.

Q:Motor: 64V/450WBattery: 16V14AH*4Controller: 64V/25AWhat do these parameters mean?How to choose an electric car?

Let me give you a rough idea:Motor: 64V/450WThe motor voltage is 64 volts. The wattage of the motor is 450 watts. The greater the more wattage motor. But at the same time, the power consumption is greater! Electric cars now have 2000 Watt motors, mounted on electric cars, and can reach 100 feet, but not far enough!

Q:What's the difference between brushless and brush motors for a storage battery?

The motor noise is normal I visited the market, a brushless motor of electric vehicle sales, to demonstrate characteristics of mute brushless motor under no-load condition, in order to prove the brushless motor than the brush motor is much superior to that in fact, the purchase of electric vehicles is not to buy air conditioning equipment, consumers don't need for it if no noise and make a decision whether or not to buy. In fact, the use of a brushless motor of electric vehicle users will know, brushless motor in no-load or low load (such as flat without wind) motor sound is very small, but when running to the heavy load such as uphill, against the wind, it tends to be a far more than brush motor "huge" the sound, even electromagnetic shaking uncomfortable, but the sound is not in the promotion process in quiet. In fact, the vehicle motor running a sound is normal, after all, it is a kind of outdoor use of transport, the provisions of the state standard for noise less than 62 decibels, the vast majority of domestic brush motor can be controlled in decibels below 55 dB, is a qualified product. Brushless motor sales guide consumers to pursue the "mute", to promote electric vehicle promotion like air conditioners, also suspected of misleading consumers, air-conditioning noise affect sleep, while the electric car noise will not affect the use of the!Three) without a series of problems of the existing motor scheme: an evening "brushless brush" wins the arbitrary will brush motor accused of "short life, large noise, low efficiency, even pointed out that" the general use of 6 months to a year to replace the carbon brush motor. "The voice of Crusade without fear! For this reason, this article also does some research on the disadvantages of brushless motor for electric bicycle.

Q:Electric bicycle motor brush good, or no good brush, what is the difference between the two?

The motor is the main driving part of the electric bicycle, which is the heart of the electric bicycle. The motor has a direct impact on the performance of electric bicycles.According to industry experts, at present, the domestic electric bicycle motor mainly has brush motor and brushless motor two kinds; brush motor and high speed and low speed points.

Q:The main circuit of the motor, yellow, blue, green, 3 outer lead and 3 power leads are connected with the color, and the control circuit 5 wires are connected with the color. The problem is that motor noise is high (especially at the start), speed is slow, riding feels underpowered, and it's very expensive. But the blue and yellow lines of the main loop and the control loop (as if the two are not clear) are switched right, and everything is ok. Why is that? Please enlighten master!!!

phase angleThe line of the motor will be turned wrong, not turn the sound, large speed is slow, but it is very difficult to idleThen change the color of the 3 wires and the 5 Holzer lines, but it depends on what happens.At present, there is a universal controller that automatically identifies the phase angle and can be used on the car. It is very convenient

Q:What is the buzz of electric motors?

Motor shake, and sometimes start or speed are likely to issue this sound, starting the motor is difficult, heavy load! Speed, it is estimated that the problem of the controller to speed up the disguised speed, resulting in motor more than the rated speed!

Q:Method for operating motor of electric vehicle

In the electric bicycle industry, the motor generally refers to the motor assembly, including the motor, heart, deceleration mechanism. Below we are talking about electric bicycles are motor assembly.I. dismantling of the motorBefore removing the motor, the motor and the controller's lead should be pulled out first, and the corresponding relationship between the lead color of the motor and the lead color of the controller must be recorded. Before opening the cover of the motor, the operating area shall be cleaned so as to prevent the sundries from being sucked into the magnetic steel in the motor. Mark the relative position of the end cap and the wheel hub. Attention: be sure to loosen the screws in diagonal order so as to avoid the deformation of the motor housing. The radial clearance between the rotor and stator is called air gap (air gap), and the air gap of the general motor is between 0.25-0.8mm. When the motor is removed and the motor is removed, it must be assembled according to the original cover mark so that the phenomenon of sweeping after the two assembly can be prevented.

Q:48V20AH how many watts of electric cars, controllers and motors?

It consists of program counter, instruction register, instruction decoder, timing generator and operation controller. It is the decision-making organ of issuing commands, that is, the operation of coordinating and directing the whole computer system.

Q:Electric car ride flat road can also, can run 40 steps, as long as an uphill boring, and bring people simply do not go. The motor is 48V350W

The original definition of magnet is the aluminum nickel cobalt alloy (i.e. AlNiCo steel in English alnico magnet, abbreviation) is composed of several hard strong metal, such as iron and aluminum, nickel, cobalt, copper, niobium, tantalum is sometimes used to make synthetic, super hardness of permanent magnetic alloy

Q:Children's electric vehicles do not go where the problem?

Then, if there is a meter, measure the voltage of the battery, is it within the reasonable range?.If the battery is good, or replace a good battery, check the drive section,
